About the Role. G2 Ops is seeking a Model-Based Systems Engineer to develop and maintain SysML models supporting mission-critical defense programs. In this role, you'll be a hands-on modeler working within an established MBSE framework, creating architecture products and model-based deliverables that drive system design, analysis, and verification activities.

You'll work alongside experienced systems engineers in a collaborative environment that values technical excellence, rigorous modeling practices, and continuous professional development.

What You’ll Do

Core Modeling Responsibilities (70%)

  • Develop SysML models capturing system requirements, architecture, and behavior, including:
    • Block definition diagrams (BDDs) for system decomposition and taxonomy
    • Internal block diagrams (IBDs) defining interfaces and data flows
    • Activity diagrams modeling operational scenarios and system functions
    • Sequence diagrams for interface behavior and message exchanges
    • State machine diagrams for mode management and system states
    • Requirement diagrams establishing traceability to stakeholder needs
  • Perform model-based analysis to support design decisions, trade studies, and technical reviews
  • Maintain model quality and consistency through adherence to modeling standards, naming conventions, and configuration management practices
  • Generate model-derived products including interface control documents, architecture views, traceability matrices, and technical reports

Collaboration & Integration (30%)

  • Coordinate with cross-functional teams (software, hardware, test, integration) to ensure model accuracy and alignment with program objectives
  • Support requirements analysis by developing and maintaining bidirectional traceability between stakeholder needs and system design elements
  • Participate in technical reviews presenting model-based architecture products to engineering teams and government stakeholders
  • Contribute to digital engineering objectives by maintaining model connections to requirements management tools and supporting documentation generation
  • Produce clear technical deliverables that communicate complex system relationships to both technical and non-technical audiences

What You’ll Bring

Required Qualifications

  • Bachelor's degree in Systems Engineering, Engineering, Computer Science, or related technical field
  • 3+ years of hands-on MBSE experience developing SysML models for complex systems
  • Demonstrated proficiency creating structural models (BDD, IBD) and behavioral models (Activity, Sequence, State Machine diagrams)
  • Experience with at least one enterprise MBSE tool (e.g., Cameo Systems Modeler, MagicDraw, Enterprise Architect, Rhapsody, or similar)
  • Understanding of systems engineering lifecycle processes including requirements analysis, architecture development, design, verification, and validation
  • Ability to establish and maintain requirements traceability within model-based environments
  • Strong technical communication skills with ability to produce clear documentation and present modeling work to diverse audiences
  • Collaborative mindset and ability to work effectively within multidisciplinary engineering teams
  • Ability to obtain and maintain required security clearance

Preferred Qualifications

  • Experience supporting DoD or government programs in aerospace, ground systems, C4ISR, or related defense domains
  • Cameo Systems Modeler or MagicDraw hands-on experience
  • Familiarity with DoDAF or UAF architecture frameworks and viewpoint development
  • Experience with model-based requirements management tools (DOORS, Jama, Polarion, or similar)
  • Knowledge of model collaboration platforms (Teamwork Cloud, 3DEXPERIENCE, or similar)
  • Exposure to parametric modeling for performance analysis and trade studies
  • Understanding of digital thread concepts and model integration across engineering disciplines
  • OCSMP (OMG Certified Systems Modeling Professional), ASEP (Associate Systems Engineering Professional), or CSEP (Certified Systems Engineering Professional) certification
  • Experience with SysML v2 or willingness to learn emerging modeling standards

Technical Environment. You'll be working in a mature MBSE environment with:

  • Established modeling framework with defined standards, templates, and best practices
  • Collaborative modeling team including systems engineers and MBSE specialists
  • Integration with requirements management and configuration management tools
  • Regular model reviews and stakeholder engagement sessions
  • Mentorship opportunities from senior systems engineers and MBSE practitioners

What Success Looks Like. In your first 90 days, you will:

  • Become proficient with our modeling environment, standards, and tool configuration
  • Contribute to ongoing model development under mentorship
  • Deliver your first model-based architecture products for technical reviews

In your first year, you will:

  • Own modeling responsibilities for specific subsystems or capability areas
  • Independently develop model artifacts supporting program milestones
  • Establish yourself as a trusted technical contributor within the engineering team
  • Identify opportunities to improve modeling efficiency and quality

Why This Role Matters. Your models will directly support critical engineering decisions for defense systems that protect national security. You'll work on technically challenging problems, develop deep expertise in MBSE practices, and have clear opportunities to grow into senior technical roles as our programs and capabilities expand.

Additional Considerations

  • This is a full-time position supporting mission-focused customer environments
  • Outside employment or activities must not create conflicts of interest with company or customer responsibilities
